Fiuheim

The materialized form of Iris' sword, he has mysterious shadow powers that Iris doesn't seem to remember. As the sword housing him was chipped in an accident, his memory is a bit jumbled. Shy and sweet around her, Fiuheim is quiet and detached towards almost everyone else. His dependence on Iris is a bit concerning, but there seems to be a deep reason for this. Despite his attachment towards her, he's willing to do what makes Iris happy, even if that means tragedy for him. [From official bio]
